Cascii is a web-based ASCII and Unicode diagram builder written in vanilla JavaScript with zero dependencies. It runs entirely in the browser by opening a single HTML file, with an optional hosted version at casci.app.

Use cases

• draw ascii diagrams in the browser
• create unicode box diagrams for documentation
• build flowcharts using plain text characters
• make ascii art architecture diagrams
• generate text-based diagrams for markdown files
• sketch system diagrams without installing software

When to choose

• you need dependency-free, offline-capable diagramming in a single HTML file
• you want ASCII/Unicode output that renders in plain text, READMEs, or code comments
• you prefer lightweight tools over heavyweight diagram apps like draw.io

When to avoid

• you need image exports (PNG/SVG) or polished vector graphics
• you want collaborative real-time editing or cloud storage out of the box
• you need a full-featured diagramming tool with shape libraries and templates
